IMPROVEMENT IN REVOLVING EARTH-SCRAPERS.

Specification forming part of Letters Patent No. 201,058, dated March 5,1878; application filed November 26, 1877.

.To all whom it may concern:

Be it known that I, BENJAMIN SLUssER, of Sidney, in the county of Shelbyand State of Ohio, have invented a new and Improved RevolvingEarth-Scraper, and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure l is a side view, showing, in dotted lines, the movementnecessary to disengage the locking devices of the scraper. Fig. 2 is aside view, showing the scraper in the act of revolving.

My invention relates to an improvement in that class of earth-scraperswhich revolve upon pivots within a handle to dump their contents.

In scrapers of this class it is necessary, in order thatthe loadedscraper shall dump easily, to locate the pivots well back upon the sidesof the scraper and near the center of its burden; but while this makesthe scraper dump easily, it also increases the liability of the same torevolve while being filled or when being transported.

My improvement is designed to secure all the advantages of this locationof the pivots without the objection mentioned; and to this end itconsists in pivoting the scraper to the handles well back and near itscenter of burden, and attaching right-angular catches to the rear endsof the bail, which operate in conjunction with two circularly-shapedlocking-irons on the forward part of the sides of the scraper, so thatthe scraper cannot revolve until the position of the handle is sochanged, at the will of the driver, as to effect the disengagement ofthe locking devices, all as hereinafter more fully described.

In the drawings, A represents the scraper, which is pivoted at a a, nearthe center of its sides, to the handles B, which latter are formed of asingle bar of iron bent twice at right angles. A

G O are spurs, attached on each side to the upper rear end of thescraper, so as to catch in the earth and complete the last eral form ofscraper.

half of the revolution of the scraper, the same being commonly employedwith this gen- D is the bail, which is pivoted at the rear to the endsof the handles, which ends extend forward past the' pivots.

Now, to secure the objects of my invention, I fasten to the rear ends ofthe bail, upon each side, upwardly-projecting catches b b, which havetheir ends bent at right angles inwardly to the scraper, and upon thesides of the scraper at this point I firmly attach two circularlocking-irons, c 0, arranged to overlap each other slightly in aparallel position, and with just space enough between them to receivethe right-angular extensions of the catches I).

Now, when the draft-strain is upon the scraper in filling ortransporting, said strain holds the catch 1) between the parallel por-Ftions of the circular irons, and locks the scraper against its tendencyto revolve.

When it is desired to dump, however, the handles are slightly elevated,which throws the bail back, as shown in dotted lines in Fig. 1, and thelocking-catches out to the rear from the circular irons, and, thescraper being then free to revolve upon its rearwardly-located pivots,the dumping is easily effected, after the manner shown in Fig. 2. Whenthe scraper is in the last part of its revolution the angleshapedcatches strike the upper circular iron and pass between the two, toagain lock the scraper in rigid position.

It will thus be seen that I secure all the advantages arising from thelocation of the pivots to the rear, or near the center of burden,without any of the disadvantages arising out of its tendency to causethe scraper to revolve at the wrong time, as when being filled ortransported.

Having thus described my invention, what I claim as new is- 1. Thescraper having the circular parallel locking-irons, combined with thebail having the right-angular catches, substantially as and for thepurpose described.

2. The combination, with the scraper havthe circular locking-irons,substantially as and ing the circular parallel locking-irons, of the forthe purpose described. handle pivoted to the scraper near its center ofburden and extended forward beyond its BENJAMIN SLUSSER' pivots,together with the bail pivoted to said Witnesses:
